To reproduce: - Show the border of a RadLabel. - Apply ScaleTransform to the root element.
This issue is declined, as the intended purpose of the ScaleTransform property is to be used to scale Telerik Presentation Framework elements, and it is not applicable to controls and their sizes. In this case, the border is not visible, as the element is being scaled with the current control size, so if the label is with size 100,100 and you scale it x2, the elements in it will be 200,200 and once the control size changes, the elements will be scaled accordingly and the border will never be visible.
